Is it just me or is the old design in place again? Yesterday when I was browsing on the videohive start page I noticed the new search bar but now it seems back to normal for me. Anyone else experiencing the same?

Its only visible for 50% of the visitors so Envato can test if there are any profound changes in user behavior. If thats not the case they will activate it for everyone.

Did you use another device or ip address yesterday to access the site? That would explain it
